COFFEE-PERCOLA'IOR.

answer.

To all whom it may concern;

Be it known that we, (3 OYD F. ANDERSON and WILLIAM C. ANDERsoN, citizens of the United States, residing at Denver, in the county of Denver and Stateof Colorado, have invented certain new and useful Improvements in Coliee-Percolators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in percolators adapted for use in' ordinary coffee pots, and an object thereof is the provision of an improved percolator which is extremely simple and ellicient in operation, and which is adapted to stand upright in a coffee pot of any diameter without the aid of supports.

A further object of this invention is the provision of a percolator which is adapted for use in an ordinary cofi'eo-pot, and in which coll ee is percolated without the aid.

of moving parts.

Still another object of this invention is the provision of a percolator comprising a percolating tube which is provided with an inverted dish-shaped foot, the upper endof the tube having a cap connected thereto in which an inverted cup is mounted; the edge of the cup being corrugated to a height above the edge of the cap, and the upper end of the tube being provided with a lurality of openings through which the uid passes into the cofl ee, whereby the fluid after passing through the 'coll'ee passes between the wall of the cap and the wall of the cup so that a quantity of the essence of the coffee is always maintained within the percolator, and this essence will be. gradu-- ally forced over the edge of the cap to the bottom of the coffee pot, whereby the time necessary to make the coffee is reduced.

\Vith these and other objects in View, our invention consists in the novel construction, combination and arrangement of parts; to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which- Figure 1 is a vertical section of a percolator constructed'in accordance with an embodiment of our invention and in appliedthe arrow; Fig. 3 is a sectional view on the line 3-3 of Fig. 1, looking in the direction Specification of Letters Extent.

of the arrow, and Fig-e is a top plan view of the percolator'as herein disclosed.

Referring more particularly to the drawing, the letterA designates a codec pot of the general construction which is provided with a cover A and the letter B designates generally the improved vpercolator. The percolator comprises a vertical tube 5 which is provided at its lower-end with an inverted dish-shaped disk or foot 6, the up per end of the tube being closed and being provided at its closed end with a plurality of vertical and circumferentially spaced openings 7. Connected to the periphery of the tube 5 below the openings 7 is a steeping receptacle 8 which is provided with an up standing annular Wall 9, the base ofsaid receptacle being provided with a plurality of spaced beads '10. An inverted cup 11 is seated within the receptacle 8, the edge of the wall 12 of the cup resting upon the beads 10, whereby the edge of the cup is spaced from the base of the receptacle. The cup 11 entirely surrounds the upper end of the'tube 5, and the lower'edge of the cup is slightly above the edge of the wall 9, where by the spaces 14 establish communication between the interior of the cup and the pot. The cup ll is provided with a suitable handle 15 by means of which the percolator may be carried, and the cup 11 fits suflicicntly tight into the receptacle 8 so as to enable the percolator to be disposed within and lifted from the coffee pot by the handle 15*without separation of the parts. The tube 5 is provided slightly above the disk or foot 6 with openings 16 through which liquid contained within the coffee pot is adapted to pass within the tube. The cup 11 is provided with a plurality of perforations 17 through which excess steam is adapted to pass so as not to retard the column of water as it rises in the tube 5, and the bottom of the receptacle is provided with a plurality of openings 18 which serve as drains.

In the practical use of the percolator, the cup 1 is removed from the receptacle and turned up so that ground codee may be placed therein,- whereupon the receptacle 8 to which the tube 5 is secured, is placed over the cup so that the edge of the wall ljl thereof engages the beads 10. The position of the percolator is then reversed and it is placed in the coflee pot so that the disk ,6

rests upon the bottom thereof, and the de-' the essence it will rise in the wall of the cup until it reaches the upper edge of the wall 9, whereupon it will overfl ow into the cofi'ee pot. As the essence is retained in the receptacle for a short time before it isdischarged into the 1 pot, it is considerably strengthened whereby the length of time necessary to make the coffee is reduced. When the coffee has been sufiiciently boiled, the essence remaining in the receptacle drains through the openings 18 into the cofi'ee pot.

What we-claim is z 1. A percolator comprlsing a tube, a receptacle provided with an upstanding wall and connected to said tube below .its upper end, said tube being formed with a plurality of perforations above said receptacle,

an inverted cup provided with a wall dis-' posed within said receptacle, mearis' for Spacing the lower edge of said cup from the bottom of said receptacle, said cup having corrugations formed on its wall and extending from its upper edge to a point above the receptacle, said receptacle and cup beingsubstantially imperforate, the base of the receptacle being provided with a plurality of restricted openings.

2. A percolator comprising 'atube, a*"r'e'- ceptacle provided with an upstanding wall and connected to said tube below its upper end, said tube having a, plurality of vertical and circumferentially spaced openings formed therein above said receptacle, an in- Wei-ted.- cup provided, with a wall mounted in said receptacle and entirely surrounding the' upper end of said tube, the wall of said cup frlctionally engaging the wall of said receptacle and the -wall of said cupbeirig provided with a plurality of corrugations extending from its free edge to a point above the free edge of *the wall of the receptacle,

'said receptacle and cup being substantially imperforate, the base of the receptacle being provided with a plurality of restricted openings 3. A percolator comprising a-tube, a receptacle provided with an upstanding wall and connected'to said tube below its upper end, said-tube having a plurality of openin'gs formed therein above said receptacle,

an inverted cup provided with a wall dis-' posed in said receptacle and surrounding 'the upper. end of said tube, the wall of said cup frictionally engaging the wall of said receptacle, and means for spacing thewall of'said cup from the wall of said receptacleat intervals, saidreceptacle and cup-bein'g substantially imperforate, the base of the receptacle being provided with a plurality of restricted openings. 7

4., A percolator comprising a tube, a sup porting disk connected to the lowerend'of' saidtube, a cup connected to said tube below its upper end, said tube having a plurality of openings therein above said cup,

an-inverted cup provided with a wall con nected to said receptaclfentirely surround ing the upper end of aid tube, said tube havingopenlngs therein adjacent said disk,

and means for spacing the wall of said cup from the wall of said receptacle at intervals, said receptacle and cup being substantially imperforate, the baSeof the receptacle being provided with a plurality of restricted openings;

In testimony whereof we hereunto afiix our signatures in the presence of two wit-j ILGSSBS.
